Research articles about Pluchea lanceolata:
Anti- cancer property: There is a growing body of evidence that suggests that the plant contains potent anti-proliferative agents that may serve as a basis for anti-cancer drugs in the near future. Basic scientific research work on the plant during the past fifteen years has increased our understanding of the biochemical composition of the plant as well as the anti tumor properties of its crude and purified extracts. Several anticancer studies on A. officinarum have focused on elucidating the molecular mechanisms underlying the preventive, protective, tumor suppressive and apoptotic activities against various types of cancers.
Anti- emetic action: Bioasay-guided fractionation of the antiemetic constituents of Alpinia officinarum was performed, and eight compounds (1−8) including a new compound were isolated. The structure of the new compound 7, which also showed antiemetic activity, was determined as 5-hydroxy-7-(4-hydroxy-3-methoxyphenyl)-1-(4-hydroxyphenyl)-3-heptanone.
Anti- oxidant activity: Ethanolic extract of Alpinia galanga showed the potent scavenging activity by DPPH method with the IC 50 value of 69.5±1.375 µg/ml, by lipid per oxidation method with the IC 50 value of 77±1.876 µg/ml, hydrogen peroxide radical scavenging activity with the IC 50 value 55±1.59 µg/ml, ABTS radical scavenging method with the IC 50 value 0.086±1.10 µg/ml.
Anti- inflammatory activity: Petroleum ether, Chloroform, Methanolic and Aqueous methanolic (1:1) extracts of Alpinia galanga Willd. were investigated for anti-inflammatory activity in carrageenan induced paw edema in Wistar rats, and compared to a positive control drug, Ibuprofen. Petroleum extract, Chloroform extract and Aqueous methanolic extracts produced 28.19, 30.13, 23.34 % of maximum inhibition, which was not significant when compared to the control. The study strengthens the claim of anti-inflammatory activity for the plant; the effect of methanolic extract may be due to the inhibition of prostaglandin synthesis.
